(Edit, seeing john's post made while I typed mine - a look at the stats now, including the error figures would be worthwhile first. End of edit).
Last thing to try is to turn the router off for at least 20 minutes. I suggest 30. Sometimes that can trigger it, and if it works it would be immediate.
If that fails then an snr reset by the Post Office is the way it usually gets sorted these days, though that is a bit of a sledgehammer to crack a nut. Yes, it does do a new 10-day training period, but in your case that isn't a worry. For more info on what it does see this page
on my website.
As long as your sync is 4000+ then you will get the 3500kbps profile back.
Good luck, and let us know how things go.
